You're shopping for groceries. Out of the blue your heart starts to race, your knees feel week, you feel like you can't breathe, like you might be having a heart attack. You wonder if you're losing your mind -- but you're not. You're having a panic attack.

About 1 in 4 people have had at least one panic attack during their lives, yet few like to admit it. Because panic manifests through physical symptoms that can mimic a heart attack, a lot of people feel shame when they go to the ER and find there's nothing wrong with them. In the absence of a test that defines panic, a lot of people worry they might be losing their mind.

Also this hour: Panic ensued in Times Square in early August when a motorcycle backfired. Fear of being caught in the crossfire of gun shots has led to a collective panic of loud noises in public places.

GUESTS:

Geraldine DeRuiter - Writer, public speaker and the author of All Over the Place: Adventures in Travel, True Love, and Petty Theft. Her blog is titled, The "Everywhereist."

But we wanted to issue that faux alert because 75 years ago tonight, as our friend Korva Coleman pointed out on the NPR Newscast, Orson Welles and his troupe of radio actors interrupted the Columbia Broadcasting System's programming to "report" that our planet had been invaded.
